“…If an operator gives a command that leads to a collision, it will be automatically blocked. The wheelchair can be controlled in different ways ranging from a joystick to an eye tracker and a high-level verbal command detector [32]. To separate different sources of commands to the actuators, a special control system was developed.…”

“…Moreover, in different conditions, the wheelchair traveled, on average, almost the same distance (1.95 ± 0.14 in Act, 1.97 ± 0.14 in Exp, 1.92 ± 0.16 in Rem). Direct comparison of estimates instead of differences has already been used by other authors who studied IB (e.g., [31,32]). For each participant, we determined the median of the estimates in every experimental condition for all five distance values.…”

Subjective Distance Estimates and Sense of Agency in Robotic Wheelchair Control

Sense of agency (SoA) refers to an individual’s awareness of their own actions. SoA studies seek to find objective indicators for the feeling of agency. These indicators, being related to the feeling of control, have practical application in vehicle design. However, they have not been investigated for actions related to the agent’s body movement inherent to steering a vehicle. In our study, participants operated a robotic wheelchair under three conditions: active control by a participant, direct control by the experimenter and remote control by the experimenter. In each trial, a participant drove the wheelchair until a sound signal occurred, after which they stopped the wheelchair and estimated the travelled distance. The subjective estimates were significantly greater when participants operated the wheelchair by themselves. This result contrasts with observations under static settings in previous studies. In an additional study on the electroencephalographic response to a sound presented at a random time after movement onset, the observed latencies in the N1 component implied that participants might have a higher sense of control when they drove the wheelchair. The proposed methodology might become useful to indirectly assess the degree of operator control of a vehicle, primarily in the field of rehabilitation technologies.
